LTC6090/LTC6090-5
140V CMOS Rail-to-Rail
Output, Picoamp Input
Current Op Amp
Description
The LTC^®6090/LTC6090-5 are high voltage, precision
monolithic operational amplifiers. The LTC6090 is unity
gain stable. The LTC6090-5 is stable in noise gain con-
figurations of 5 or greater. Both amplifiers feature high
open loop gain, low input referred offset voltage and noise,
and pA input bias current and are ideal for high voltage,
high impedance buffering and/or high gain configurations.
The amplifiers are internally protected against over-
temperature conditions. A thermal warning output, TFLAG,
goes active when the die temperature approaches 150°C.
The output stage may be turned off with the output disable
pin OD. By tying the OD pin to the thermal warning output
(TFLAG), the part will disable the output stage when it is
out of the safe operating area. These pins easily interface
to any logic family.
Both amplifiers may be run from a single 140V or spit
±70V power supplies and are capable of driving up to
200pF of load capacitance. They are available in either an
8-lead SO or 16-lead TSSOP package with exposed pad
for low thermal resistance.
